Class ConcurrentMessageDigest

java.lang.Object
org.apache.tomcat.util.security.ConcurrentMessageDigest

public class ConcurrentMessageDigest extends Object
A thread safe wrapper around MessageDigest that does not make use of ThreadLocal and - broadly - only creates enough MessageDigest objects to satisfy the concurrency requirements.

    • init

      public static void init(String algorithm) throws NoSuchAlgorithmException
      Ensures that digest(String, byte[][]) will support the specified algorithm. This method must be called and return successfully before using digest(String, byte[][]).
      Parameters:
      algorithm - The message digest algorithm to be supported
      Throws:
      NoSuchAlgorithmException - If the algorithm is not supported by the JVM
